The IPCC claimed that the Little Ice Age was just in the Northern Hemisphere. This research call that bit of factless story telling into question. The LIA was global.

The U.S. has a research station located at the WAIS divide where scientists associated with the Scripps Institution of Oceanography conducted an analysis to determine the Little Ice Age impact on the southern polar region.

“The authors (Orsi et al.) write that “the Northern Hemisphere experienced a widespread cooling from about 1400 to 1850 C.E., often referred to as the Little Ice Age (hereafter LIA),” which they describe as “the latest of a series of centennial scale oscillations in the climate,”…three researchers, all from the Scripps Institution of Oceanography, report determining that “the WAIS Divide was colder than the last 1000-year average from 1300 to 1800 C.E.,” and they say that “the temperature in the time period 1400-1800 C.E.” – which meshes well with the chronology of the LIA in the Northern Hemisphere – “was on average 0.52 ± 0.28°C colder than the last 100-year average.”…stating that their result “is consistent with the idea that the LIA was a global event, probably caused by a change in solar and volcanic forcing…” [Anais J. Orsi, Bruce D. Cornuelle, Jeffrey P. Severinghaus] 2012: Geophysical Research Letters]

Russ, I just watched a program. It was Nova on PBS titled; Earth From Space. In the program, it shows all of the ocean currents on the planet are controlled by the antartic ocean,and how the planet climate works via the sun,the oceans,and the atmosphere. Which got me thinking. Based on the last three years of the antartic ice growing, could this possibly be slowing the ocean currents down? And getting the jet stream to do things we have not seen in modern time? We”ll have to watch and monitor that very closely. With all the technology we have today, we may be watching ourselves slide back into a little ice age again! This is something we can not control, but we can only watch. To even say or make a statement that man can or is in control of the climate, I say to them, if he is, then STOP THE COMING LITTLE ICE AGE!! So we will not have crop growing problems, and food shortages. Here’s the link to the program http://www.youtube.com/watch?v=RPRofVIQ5io This video sums it all up. thanks, Anthony

Thanks fo the link. We usual watch NOVA, but missed this program. I think we are watch the early stage of the next ice age. It takes a generation to really start acceleration. The antarctic ice growth and the rapid return of arctic ice maybe some early indicators. We are living in interesting times.

Your welcome Russ.This time around, it may be sooner than a generation. There are alot of factors involved. 1.) The sun. 2.)The AMO and PDO. 3.) The earth’s magnetic field. 4.) More clouds reflecting sunlight back into space. 5.) The coming of the cooling of the oceans world wide. I happen to come across another video of both climatologist Art Horn and Joe D’Aleo. They both seem to agree that temperatures are going to decline once the AMO turns to negative. This will happen by the end of this decade or maybe sooner give or take acouple of years. Here’s the link http://www.youtube.com/watch?v=r9OlC37-_n8 I enjoyed whatching it. I hope you will to. Joe D’ Aleo has a website called ICECAP.US you can find that here> http://icecap.us/ And I agree with you, we are living in a time that no one living today has experienced since the last minimum. We where all used to the warmth of climate. Now that is about to change. As far as the other program on nova, it’s really something how we know now how the earth’s climate works, and they show it before your eye’s and still say man is efecting the climate. But they gave it away, and got caught in a lie, when they said, 6,000 year’s ago the sahara desert had ocean water. Certainly man was not responsible for the sahara drying up, as there were less people living back then. So how did it really dry up? We know from ice core drilling records, the earth goes into an ice age when there is less water vapor in the atmosphere. We also know the desert is growing. This should be an indicator that, A.) The planet is losing water, or B.) The ice caps and glaciers are growing. And with the continuing drought in the united states and parts in of the world the message is clear, we are on the next temperature drop! The sun is not strong enough to cause enough evaporation of water on the planet and has not for the last 3,000 years. I would like your opinon on this Russ. What do you think? Anthony
